Tactors are small transducers, designed to optimize skin response to vibration. These devices are used to provide communication to replace or supplement audio and visual input, especially under circumstances where audio and visual cues can be missed. EAI's electromechanical tactors provide orders of magnitude increase in output over prior devices of this type, while still being small, lightweight and reliable. EAI has developed a range of Tactors and a variety of driver boards that make Tactile Displays and Tactile Situation Awareness Systems (TSAS) viable for a variety of demanding military, medical and commercial applications.
